Abstract

The invention relates to a media retrieval method and device, and the method comprises the steps: obtaining a media feature of a to-be-retrieved media as a first media feature which comprises a plurality of first media feature monomers; performing first ranking on a plurality of known media according to each single first media feature monomer, and taking out the first k known media as a first candidate media set according to a result of the first ranking, where k is a positive integer; and performing second ranking on the first candidate media set according to the plurality of sequentially arranged first media feature monomers, and taking out the first n first candidate media as a retrieval result according to a result of the second ranking, where n is a positive integer.

Description

technical field [0001] The present disclosure relates to the technical field of media processing, in particular to a media retrieval method and device. Background technique [0002] Media features such as video features and audio features (or called media fingerprints) and feature-based media retrieval are widely used in today's "multimedia information society". Media retrieval was initially applied to listening to songs and recognizing songs, that is, input a piece of audio, and by extracting and retrieving the fingerprint features of the piece of audio, the corresponding song can be identified. In addition, media retrieval can also be applied to content monitoring, such as media deduplication, retrieval-based audio advertisement monitoring, media copyright, etc. [0003] Existing media retrieval methods have the problems of poor accuracy and slow speed, which will consume a lot of computing resources and storage resources. Contents of the invention [0004] The purpose...
